General Approach for Scalability Business Mashups 2008: System Requirements & Scalability When optimizing performance, focus first on getting servers with the fastest possible CPUs. Second, look closely at memory utilization and ensure there is enough. Then, consider multiple processor configurations. These principles should be applied to servers when both scaling vertically and scaling horizontally. In the end, any single Serena Business Mashups operation happens fastest when CPU speed, network bandwidth, and available memory are high. Using the fastest possible CPU at the client, server, and database tiers result in the best end user experience. The following chart illustrates scalability zones for Serena Business Mashups.

In this chart there are four zones. Zone 1 represents low activity and simple configuration and usage patterns. Zone 4 is at the highest end of the spectrum. It represents high user load and complex data and usage patterns.

This table can be used to determine appropriate server configurations based on usage patterns and expected number of active users. The configuration recommendations are the result of analysis of data collected as part of the rigorous Serena Business Mashups acceptance and certification process. The data set used was of Enterprise size and reflected configurations common to many of our customers.

An active user is defined by a user in the system who is actively performing work (e.g., two users running a report at the same time). More users can be logged into the system but are not considered active until they are performing some activity. With this definition you can determine your usage pattern and the number of processes that you anticipate to consider a hardware configuration that might fit your needs. If for example, if you want to support a population of 250 users and you believe at any one time you will have 25 users performing moderate operations (submitting new requests, updating records, reporting, querying for a record, etc.) then Zone 1 would be the starting point for the hardware you might consider. If you had a 20,000 user population to support, Zone 3 at 300 concurrent users might be appropriate for you.
